Tasty good for you beverage
Flavor Name: Black Raspberry, Size: 17 Fl Oz (Pack of 12)
So refreshing and tasty. I gave up Pepsi due to the caffeine and found these so satisfying. The taste is great and just enough fizzy! A great value and the bottle size is good for more than one if you wish. No sugar load and theres vitamins too. The case is 12 bottles and had no leaks or damage! Quick delivery too!

Smooth Daily Brew with Rich Flavor Variety – Easy, Consistent Nespresso Coffee Experience
Flavor Name: Medium and Dark Roast Variety Pack, Size: 10 Count (Pack of 3)
I’ve been using this variety pack for my daily coffee, and it’s been a really convenient way to switch between different roasts without thinking too much about it. What I like most is the consistency in flavor and brew quality. Every pod comes out smooth, and the taste is balanced whether I go for a medium roast or something darker. The darker ones feel stronger and more intense, while the medium roasts are a bit lighter and easier for everyday drinking. The 7.8 oz size is perfect for a fuller cup, especially in the morning when I don’t want anything too small. It brews quickly, which makes it great for busy days. One thing I noticed is that the variety helps if you don’t want to commit to just one roast you can rotate depending on your mood. Overall: reliable, easy, and a good mix of flavors for everyday coffee without any hassle
